Ccna-2v7.0 Case Study -rev B-

For those preparing for the 200-301 CCNA exam or completing this case study, several platforms provide guided walkthroughs and lab files:

R1(config)# access-list 100 deny ip 192.168.20.0 0.0.0.255 192.168.10.0 0.0.0.255 R1(config)# access-list 100 deny ip 192.168.20.0 0.0.0.255 192.168.99.0 0.0.0.255 R1(config)# access-list 100 permit ip any any R1(config)# interface g0/0/1.20 R1(config-subif)# ip access-group 100 in

After completing Rev B, review your configuration against the official scoring rubric. If possible, have a peer review your ACL logic. Then, document every interface IP, VLAN mapping, and route in a network diagram – that documentation is a habit of successful professionals.

The primary objective of the CCNA 2 v7.0 case study is to allow students to complete a full network design, implementation, and troubleshooting project using the skills gained throughout the SRWE course. The project is typically broken down into several distinct phases:

Configure all inter-switch links as trunks. Explicitly define the native VLAN to prevent VLAN hopping attacks: ccna-2v7.0 case study -rev b-

: The case study often requires coordinating these floating routes with HSRP to provide a redundant gateway for end devices, ensuring that even if a router or link fails, the user traffic seamlessly transitions to the backup path.

: On the Main Router or Multilayer Switch (MLS), configure sub-interfaces (for Router-on-a-Stick) or Switched Virtual Interfaces (SVIs) to allow communication between different VLANs. 3. Implement Layer 2 Security Secure the switch access layer against common attacks. For those preparing for the 200-301 CCNA exam

To carry multiple VLANs between switches, trunk links must be configured using IEEE 802.1Q encapsulation. The case study typically requires trunking on the interfaces connecting the two switches and between the switch and the router.

A design is only as good as its verification parameters. Use these core Cisco IOS commands to check deployment success:
